NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW:
FreeBSD 13.x has many debugging features turned on, in both the kernel
and userland. These features attempt to detect incorrect use of
system primitives, and encourage loud failure through extra sanity
checking and fail stop semantics. They also substantially impact
system performance. If you want to do performance measurement,
benchmarking, and optimization, you'll want to turn them off. This
includes various WITNESS- related kernel options, INVARIANTS, malloc
debugging flags in userland, and various verbose features in the
kernel. Many developers choose to disable these features on build
machines to maximize performance. (To completely disable malloc
debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild
world, or to merely disable the most expensive debugging functionality
at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".)
